Biological aspects and population dynamics of the European pilchard Sardina pilchardus (Walbaum, 1792) in the southeastern Mediterranean waters

Journal of Fish Biology, Volume 108, Issue 4, Page 1072-1086, April 2026.
Abstract The European pilchard, Sardina pilchardus, is a key small pelagic fish sustaining Mediterranean ecosystems and fisheries. This study represents the first comprehensive biological and population dynamics assessment of the European pilchard by applying the length‐based spawning potential ratio (LB‐SPR) approach to S.

High‐Throughput DNA Sequencing Reveals Gastric Content Composition and Inter‐Specific Variation in Pampus Fishes

Ecology and Evolution, Volume 16, Issue 3, March 2026.
In this study, we employed high‐throughput sequencing of environmental DNA (eDNA) to conduct an analysis of the gastric contents composition and relative abundance from samples of P. argenteus and P. punctatissimus collected at the Jimiya Fish Pier in Qingdao, Shandong Province, and P. cinereus collected at the Qinglan Port in Wenchang, Hainan Province.

Primer Length in Reverse Transcription Determines Biodiversity Recovery and Reproducibility in eRNA Metabarcoding

Environmental DNA, Volume 8, Issue 2, March/April 2026.
Primer length for reverse transcription significantly affects eRNA‐based biodiversity recovery and community structure. Shorter primers, particularly N4 and N5, in random priming and medium‐length primers, particularly T20, in oligo(dT) priming demonstrate superior performance, especially in detecting the rare biosphere.

Dieta da toninha (Pontoporia blainvillei) na costa norte do Espírito Santo, Brasil

Biotemas, 2019
A toninha (Pontoporia blainvillei) é considerada a espécie de golfinho mais ameaçada da costa do Brasil. As populações de toninha que ocorrem no litoral norte do estado do Espírito Santo constituem populações isoladas, separadas por um hiato geográfico ...

Evaluating the Potential for Citizen Science Divers to Monitor Fish Biodiversity Through Passive eDNA Collection

Environmental DNA, Volume 8, Issue 2, March/April 2026.
Passive capture of eDNA can be used as a tool for citizen scientist SCUBA divers to supplement visual surveys for marine species detection and is particularly useful for species that are rare or visually inaccessible to divers. ABSTRACT Environmental DNA (eDNA) marker gene sequencing, or metabarcoding, can be a powerful tool for monitoring marine ...

A new possible breeding site of Alosa fallax (Lacépède 1803) (Actinopterygii: Clupeiformes: Alosidae) on the Tyrrhenian coast of Central Italy

Natural History Sciences
The River Mignone (Tarquinia, Viterbo, central Italy) is one of the best preserved watercourses in Lazio. Here, in April and May of the years 2020-2023, a conspicuous contingent of Alosa fallax (Lacépède 1803) was reported. The frenetic behaviour of the

The oldest acanthomorph fossil (Actinopterygii, Teleostei) from the Early Cretaceous of Gondwana (Morro do Chaves Formation, Sergipe–Alagoas Basin, NE Brazil)

Papers in Palaeontology, Volume 12, Issue 1, January/February 2026.
Abstract This paper presents the discovery of †Gondwanacanthus decollatus, a new genus and species of Early Cretaceous deep‐bodied fish from the late Barremian or early Aptian Morro do Chaves Formation in the Sergipe–Alagoas Basin, northeastern Brazil. It represents the first record of Acanthomorpha in Early Cretaceous Gondwana.

Anthropogenic Factors Drive the Depletion of Fish Functional Β Diversity Within and Outside Two National Reserves in the Peruvian Amazon

Aquatic Conservation: Marine and Freshwater Ecosystems, Volume 35, Issue 12, December 2025.
ABSTRACT Understanding the impact of human activities on fish communities is critical for the effective conservation of Amazonian ecosystems. In this study, we sampled environmental DNA (eDNA) from 17 sites (lakes and rivers) in two Peruvian national reserves, Pacaya‐Samiria and Allpahuayo‐Mishana, using a metabarcoding approach with four genetic ...

Multiple freshwater invasions of the tapertail anchovy (Clupeiformes: Engraulidae) of the Yangtze River [PDF]

Ecology and Evolution, 2019
AbstractFreshwater fish evolved from anadromous ancestors can be found in almost all continents. The roles of paleogeographic events and nature selection in speciation process often are under focus of research. We studied genetic diversity of anadromous and resident tapertail anchovies (Coilia nasus species complex) in the Yangtze River Basin using 4 ...

Morphological development of Anchoviella vaillanti (Steindachner, 1908) (Clupeiformes: Engraulidae) larvae and early juveniles

Neotropical Ichthyology
The considerable similarity in the early life stages of different fish species makes egg and larvae identification in fishery biology and ichthyoplankton surveys a difficult task.
